Property on model attribute set in one controller method is not available in another controller method

Question

Following contains the code inside my controller class , i am using the method public String getRegistrationForm(Map model) to return a jsp-page with a spring form on it , in this method i am setting userTab.setIsMfaEnabled(new Boolean(true)) , upon submitting the form the method : public String registerUser(@ModelAttribute("user") UserTab user , BindingResult results , Map model) is invoked as the handler method , but in this method the property 'isMfaEnabled' of user attribute set in the previous method is null and the line:System.out.println("user.getIsMfaEnabled() is nul"); is printing in the logs . Kindly tell me what is wrong here .

@Controller
@RequestMapping("/register")
public class RegisterUserController {   
    @Autowired
    RegisterUserService registerUserService;

    @RequestMapping(value = "/registeruser.action" , method =     RequestMethod.POST)
    public String registerUser(@ModelAttribute("user") UserTab user , BindingResult results , Map model){
        System.out.println("executing regsiterUser ");
        if(user == null)
           System.out.println(", user is null");
        if(results == null)
           System.out.println("results is null");

        UserTabValiator userTabValidator = new UserTabValiator();
        if(user.getIsMfaEnabled() == null)
            System.out.println("user.getIsMfaEnabled() is nul");
        userTabValidator.validate(user, results);
        if(results.hasErrors()){
           return "registeruser";
        }
        try {
            boolean val = registerUserService.isExistingUsername(user.getLoginName());
            if(val){
                System.out.println("username already exists");
                model.put("message", "username already exists");
                return "registeruser";
            }
           if(!val){
               model.put("username", user.getLoginName());
               model.put("message", "registration success ... ");
               return "registrationsuccess";
           }            
        } catch (Exception e) {
            System.out.println("exception thrown");
            e.printStackTrace();
            return "errorpage";
        }
       return "errorpage";
 }


   @RequestMapping(value="/registeruser.view", method=RequestMethod.GET)
   public String getRegistrationForm(Map model){
       System.out.println("executing getRegistrationForm");
       if(registerUserService == null)
       System.out.println("register user service is null");
       try{
         ArrayList allMfaQuestions = (ArrayList) registerUserService.getAllMfaQuestions();
        UserTab userTab =  new UserTab();
        userTab.setIsMfaEnabled(true);
        model.put("user", userTab);
        model.put("message", "register new user");
        model.put("allMfaQuestions", allMfaQuestions);
        return "registeruser";
       }
       catch(Exception e){
           e.printStackTrace();
           model.put("user", new UserTab());            
           model.put("message", "unable to get MFA questions");
           return "registeruser";
       }
    }

Add code in the JSP form to bind the value of isMfaEnabled
